Spurs play at Norwich on Tuesday before heading to Swansea on New Year's Day and then play West Brom on January 3 at White Hart Lane.
"We have to do whatever it takes to win those games if we are going to finish in the top four. Otherwise, forget about it," the striker said.
"We have to keep our head up, keep doing our thing, keep enjoying ourselves. Now we are going to play Norwich on Boxing Day. We have to do everything we have to win that game.
"Then we have Swansea away, I'm not saying they are going to be easy games but if you want to be in the top four those are the types of games that you have to win home or away."
